Stoddart, Fond du Lac, Wis., assiguor toBestt Rollr Inc., Fond du Lac, Wis., a corporation of Wisconsin FiledJan. 10, 1968, Ser. No. 696,798 Int. Cl. B25g 3/30; B44d 3/28 US. Cl.306-30 3 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTIONField of the invention This invention relates to frames and handles forpaint rollers and the like and particularly to such frames and handleswhich are adapted to be fitted with an extension, such as a mop stick,so that the operator may use the device on high places without need forladders, scattolding, etc.

Description of the prior art In the prior practice, as exemplified byUS. Patents: 2,984,853, 3,008,167, a manually grasped handle secured tothe frame is preferably made of suitable wood or frangible materialbecause such material is cheaper and provides a more secure grippingsurface. However, such frangible handles when provided with an internalcounterbore in the outer end to receive an extension often split orbreak when so used.

In the application of Louis Tigerman S.N. 493,520 now Patent No.3,371,367 and assigned to the same assignee as this application, thereis a threaded metal socket which seats in a counterbore in the end ofthe handle and is directly secured to the solid metal portion of themetal frame to avoid pressure on the walls of the counterbore.

Summary of the invention The essence of this invention is the passing ofthe handle mounting portion of the metal frame through the frangiblehandle and rigidly securing to the outer end of such handle mountingportion an internally threaded metal socket which seats against the endof such handle to form a two-part handle. When the extension is fittedin such socket the bending strain due to normal use of the device isabsorbed by such metal parts and is not communicated radially to anypart of the frangible handle.

BRIEF DESCRIPTION OF THE DRAWING In the drawing:

FIG. 1 is a plan view of a paint roller having a frame and handleembodying the present invention;

FIG. 2 is an enlarged sectional view taken on the line 2-2 of FIG. 1showing in detail the handle portion of the frame, the frangible handle,and the internally threaded metal socket which forms a part of thehandle arranged in accordance with this invention; and

FIG. 3 is an exploded view of the squared outer end of the handleportion of the frame, the inner and outer end of the frangible handle,the internally threaded metal socket forming a part of the handle with asquare open- "ice ing on its inner end, and the fastening means all asshown in FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawing andfor purposes of illustrating one application thereof, a metal rod-likeframe, indicated generally at 10, and a two-part handle consisting of afrangible handle 24 and an internally threaded metal socket 28 embodyingthis invention are shown associated with a paint roller 18 of well-knowndesign. The frame, as customary for such use, has a shaft portion 12which rotatably carries the paint roller 18, or other work performingmember, connected by a clearance portion 14 to an ofiset portion 16,from which extends a handle mounting portion 20.

This handle mounting portion 20 is provided with spaced nibs 22 (seeFIG. 2) which are staked out from the body of such portion. These nibsengage with the manually grasped frangible handle 24 to prevent itsaxial displacement and rotation relative to such mounting portion.

The two-part handle consists of a frangible handle 24 and the internallythreaded socket 28. The frangible handle 24, which is manually graspedfor operation of the device at normal operator heights, in thisinvention is made of suitable inexpensive wood or other frangiblematerial. Such handles provide a most satisfactory grip for the user andare most acceptable to the trade. However, if such handle is a member ofa bending resistance chain of components including an extension for useof the device above normal operator heights, it Will frequently split orbreak even in normal use. Therefore the handle 24 is provided with abore 25 extending longitudinally through such handle. The length of thehandle mounting portion 20 from the nibs 22 to its outer end 25 and thelength of the bore 26 in the handle 24 are proportioned so that whenhandle 24 is mounted on such portion with the nibs 22 in press fittedembedded engagement with the wall of the bore 26, a square end 27 on theouter end 25 will project slightly beyond the outer end of such bore.

The means for fastening an extension, such as a mop stick (not shown),to the roller carrying frame 10 which will exclude the frangible handle24 as a component in resisting bending strain during use of the devicewith an extension, consists of an internally threaded metal socket 28which has a closed end 29 provided with a square opening 30 throughwhich the square end 27 of the handle mounting portion is fitted. Thesquare end is provided with a threaded hole 31 and a screw 32 isthreaded there in to hold the end 29 tightly on the square end 27 and inabutment with the outer end of handle 24. This socket is adapted todemountably receive threaded end of an extension and form a jointtherebetween which will resist bending. Thus any flexing due to thebending stress transmitted between the roller 18 and an extension fittedin the socket 28 will be directly resisted by (1) the metal .rodmaterial of the frame 10, (2) the rigid joint between socket 28 and theouter end 25 and outer end of the handle 24, (3) the walls of the metalsocket 28, and (4) the extension. The frangible handle 24 is thus not acomponent in this bending chain and is not subjected to bending stresseswhich tend to split it. While it is subjected to axial compression thishas no tendency to split the handle.

The metal socket 28 may be of die cast metal and has relatively thickwalls and a thick closed end 29 to provide adequate strength. Itsdiameter is the same as that of the frangible handle 24 and thus itforms a small part of such handle. While not essential the closed end 29may have a slightly raised area 34 which interfits with a correspondingrecess in the outer end of the handle 24.

I claim:

1. A frame and handle for a roller or other work performing membercomprising:

a frame having a solid metal mounting portion for a handle, said portionhaving a square projection on its outer end, said projection havingthreaded means thereon, said portion having laterally projecting nibs;

a frangible handle provided with longitudinally extending bore, saidmounting portion extending through said bore with said square projectionextending beyond said bore, said nibs being partially embedded in oneend face of said frangible handle;

a cylindrical internally threaded metal socket having a closed inner endprovided with a square opening through which said square projectionextends, said socket closed inner end being in engagement with the otherend face of said frangible handle, said socket having an outer open endleading to said internally threaded portion whereby said socket isadapted to be removably attached to an extension; and

means cooperating with said threaded means and engaging the closed innerend of said socket so as to hold said socket closed inner end rigidly onsaid square projection and in tight abutment with the other end face ofsaid frangible handle.

2. A frame and handle as claimed in claim 1 in which said metal sockethas the same outer diameter as said frangible handle to form a smallpart thereof.

3. A frame and handle as claimed in claim 2 in which the outer end ofsaid frangible handle and the inner end of said socket have complementalinterfitting raised area and recess.
